Modal verbs in English communicate delicate shades of meaning, there being a large range of verbs both on the necessity side (must, have to, should, ought to, need, need to) and the possibility side (can, may, could, might, be able to). They therefore constitute excellent test ground to apply and compare different methodologies that can lay bare the factors that drive the speaker’s choice of modal verb. This book is not merely concerned with a purely grammatical description of the use of modal verbs, but aims at advancing our understanding of lexical and grammatical units in general and of linguistic methodologies to explore these. It thus involves a genuine effort to compare, assess and combine a variety of approaches. It complements the leading descriptive qualitative work on modal verbs by testing a diverse range of quantitative methods, while not ignoring qualitative issues pertaining to the semantics-pragmatics interface. Starting from a critical assessment of what constitutes the meaning of modal verbs, different types of empirical studies (usage-based, data-driven and experimental), drawing considerably on the same data sets, shows how method triangulation can contribute to an enhanced understanding. Due attention is also given to individual variation as well as the degree to which modals can predict L2 proficiency level.

In this first book-length treatment of MELF, the authors assert that MELF represents an important contribution to our understanding of English as a Lingua Franca (ELF), in that existing ELF research has been limited to relatively low stakes communicative situations, such as interactions in business, academia, internet blogging or casual conversations. Medical contexts, in contrast, often represent situations calling for exceptional communicative precision and urgency. Providing both evidence from their own research and analysis from (the limited number of) existing studies, the authors offer a counterpoint to the optimism regarding communicative success prevalent in ELF. The book proposes a theoretical perspective on how the various features of healthcare communication serve as important variables in shaping interaction among speakers of ELF, further enlarging our understanding of this emerging sub-field.
